Five instances of And 20. trigger 21, sixth element l / i 2g. the second trigger 23, from the first to the fourth elements OR 24-27, as well as Og.ok In recording information

The first switch 13 (Fig. 2) includes a relay 29 with a winding, a moving contact 291 and a fixed contact 29, d and 29,

A time sensor 14 (FIG. 3) constitutes a master oscillator 30, a first frequency divider 31, consisting of five serially connected decimal counters 32-3 R, an inverter 37 with a phase-pulse information presentation, and a second frequency 38, consisting of serially connected dectidy sensors 39 and 41 and one-shot 41 and 42.

The second switch 19 (FIG. 4) contains control buttons 43-46, a common bus 47, a decimal code converter 48 in binary, triggers 49-52. 53 decimal binary code converter, digital indicator 54 and elements AND 55 -58

 / construction works as follows

When the device is turned on, the sensor 14 operates from the outputs of which short signals 1 arrive at the circuit. At the same time, from the first output of the time sensor 14, signals of a higher frequency follow than with its signal -. and third output signals 1 s

the second output of the time sensor 14, mine connected contacts 292 and 29i of the first switch 13, follow the seventh input of the unit 28 and interrogate the first to the fourth 15-18, the fifth 20 and the sixth 22 elements I. the first 21 and second 23 triggers, as well as arrive at the second input of the second switch 19,

At the operating mode of the machine come

signals from the outputs of the third sensor 3, the tension of the wire, the first sensor 1 of the wire consumption and the second sensor 2 of the electric power consumption. The signal of the third sensor 3 is amplified by amplifier 4, converted

analog-to-digital converter 5 and follows as a combination of signals 1 and O for conversion by block 11 and indication by block 12, as well as to the first inputs from the first to fourth elements of AND 15-18.

The signal after the amplifier 4 should be on the threshold element 8, the output of which 1 is fed to the first input of the fifth element And 20.

The signals from the bottom of the first sensor 1 arrive at the first input of the trigger 21, transfer it to the state O, and also follow the fault input of the first conversion unit 6. This triggers the inverter 9, the output of which produces an enable signal that goes to the second inputs first to fourth 15-18 and an additional 20 elements And, as well as to the first input of the second switch 21. Short signals from the output of the second sensor 2 are sent to

the trigger input 23, its transfer to the state O, and also follow to the reset input of the converter unit 7, switching it to the state O. This triggers the inverter 10, the output of which produces the enable signal 1, which is fed to the first input of the sixth element AND 22

In the operating mode, from the outputs of the elements OR 24-27, the second - to the fifth "inputs of the block 28 receive a combination of signals

G and O, characterizing the value of the tension force of the wire. The seventh, eighth and ninth inputs of block 28 receive signals G, and the first and sixth inputs - signals 1 or O, which characterize the consumption of wire and electricity.

When the machine is idle (stopped) with the motor running, when the third wire tension sensor 3 generates a signal, the second wire consumption sensor 2 outputs the signal Q (the pickup roller does not rotate), the second power consumption sensor 2 initiates signals 1 or 0, the device works as follows .

At the output of block b, CIT-1 is generated, since the short counting pulses 1 are received from the first output of the time sensor 14 to its second one. At the same time, the winding of the relay 29 of the first switch 13 is triggered from signal 1 from the output of the first conversion unit 6 (figure 2) Azyvg connection contacts 29i and 0z. At the switch 29 of the first switch (3 followed by the low-frequency signals 1 of time sensor 14. At the output of the inverter 9, the signal C prohibits the operation of nepn / lo - the fifth elements 15-18 and 20 Lr which the switch 9 opens). The operator takes a decision about the form of a simple machine, t-pressing, for example, button 43. At the same time, at the output of converter 48 of decimal code to binary, you set a combination of signals 1 and 0 or with which the corresponding triggers are triggered by 52 52 si ia- lam 1. A binary code converter 53 in desg, primary and digital indicator 54 are activated. At the corresponding -.r .. the resolving signals 1 are given to the first inputs of the elements Ius 1 enavl.

Short signals 1 pykhoda second sensor 2 power consumption r. They are transferred to the first input of the second flip-flop 23, transferring the latter to the O state, and then to the fault input of the second conversion unit 7, switched from the O state. In this case, the second inverter 10 triggers, at the output of which the enabling signal 1 appears, The first input element is T.

When the machine is idle with a working electric motor (Fig. BB), the second - fifth inputs (from the outputs of the OR elements 24-27) of the block 28 receive a combination of signals 1 and O, which characterizes the view of the machine itself. The sixth and first inputs of block 28 are followed by the signals O, the eighth and ninth inputs of which receive signals 1 or O, and the seventh input signals 1.

When the machine is idle with the motor turned off, when the signal O is set at the output of the second power consumption sensor 2, the signals E are received at the eighth and ninth inputs of the unit 28, because the signal 1 is set at the output of the second conversion unit 7 and the output of the second inverter 1C prohibitory signal O.

In the mode in question (Fig. 5B), the second - fifth inputs (from the output of the OR elements 24-27) of the block 28 receive a combination of the signals O and 1, which characterizes the view of the machine itself. The sixth, first, eighth and ninth inputs of block 23 are followed by the signals O, and the seventh is always signals i.

At the end of a shift or cycle of pinging (testing) a gyatu fi IUKO machine, I 28 is handed over to a computer center for subsequent processing of accumulated g-innt-.x 5 on a computer.
